“…As alterações motoras do esôfago provocadas pela laringectomia também podem estar envolvidas (3) . Os resultados demonstraram que para produzir a voz esofágica, o paciente precisa reter ar no esôfago o que causa aumento da pressão intraesofágica, e expeli-lo através da transição faringoesofágica.…”

“…A metodologia de estudo da motilidade do esôfago foi previamente descrita (1,2) . Utilizou-se um cateter de polivinil de oito canais com diâmetro externo de 4,5 mm e diâmetro interno em cada canal de 0,8 mm (Arndorfer Specialties Inc., Greeendale, Wisconsin, EUA).…”

“…A transição é o local onde é produzida a vibração necessária para a voz (9) . As contrações esofágicas desencadeadas pela deglutição estão alteradas após laringectomia (2) , com diminuição da amplitude da contração e aumento do número de contrações não-peristálticas. Ainda não é esclarecido o que ocorre com a pressão intra-esofágica no momento em que há a produção da voz.…”

“…In the present study we determined the values of sound intensity regardless of the type of voice and noted that there is a relationship between sound intensity and intraluminal esophageal pressure 19 . There has been a concern about characterizing good or poor speakers according to the properties of esophageal motility observed in total laringectomees [13][14][15][16] . However, little is known about the influence of esophageal motility on vocal intensity.…”

“…The aerodynamic characteristics of tracheoesophageal voice production are determined by the aerodynamic factors of the prosthesis and by the characteristics of the esophagus and of the cricopharyngeal segment, which affect the determination of good and poor speakers [13][14][15][16] . However, it is still necessary to obtain data indicating which properties of the esophagus and of the cricopharyngeal segment specifically influence the vocal parameters.…”

PURPOSE:To evaluate and correlate the amplitude of esophageal contractions triggered by swallowing water with dynamic extension and habitual, strong and weak sound intensity in total laryngectomees wearing a tracheoesophageal prosthesis. METHODS:Thirty total laryngectomees using tracheoesophageal voice with a phonatory prosthesis were evaluated by measuring the amplitude of contractions in the proximal, middle and distal esophagus and the pressure of the pharyngoesophageal transition by manometry. In order to measure vocal intensity the subject was asked to emit phonation of the vowel /a/ at habitual, strong and weak intensity which was captured with a sound pressure meter. Dynamic extension was calculated by subtracting strong intensity from weak intensity. RESULTS:A positive correlation was observed between contraction amplitude and dynamic extension in the proximal (rho: 0.45; p=0.01) and distal (rho: 0.41; p=0.02) esophagus There was no correlation with other parameters.. Total laryngectomees wearing a phonatory prosthesis with a dynamic extension above 21 dBNPS had greater contraction amplitude than laryngectomees with a dynamic extension below this value. CONCLUSIONS:There was a positive correlation between pressure amplitude in the proximal and distal esophagus and increased dynamic extension. The individuals with normal dynamic extension had greater contraction amplitude in the proximal esophagus than individuals with dynamic extension lower than the expected values for age .
